11 Celebrities that you never knew had a twin

1. Jon and Dan Heder

Everyone knows Jon as Napoleon Dynamite, but no-one knows he has a twin brother.

2. Laverne Cox and M Lamar

The transgender Orange is the New Black star plays a transgender character in the show, and her brother (a goth musician and artist) played Cox's character in the pre-transitioning flashback scenes.

3. Gisele and Patricia Bündchen

The supermodel's twin sister was also blessed with beautiful genes.

4. Hunter and Scarlet Johansson

Hunter quite regularly joins his twin sister on the red carpet, and everyone is sure to notice the 30cm height difference between them.

5. Michael and Ashton Kutcher

Ashton has a twin brother with cerebral palsy who underwent heart surgery at just 13 years of age. Now, he's giving motivational speeches for young people living with disabilities.

6. Rami and Sami Malek

The Mr Robot actor indeed has a twin brother, who has a respectable job as a teacher, thank you very much.

7. Marissa and Giovanni Ribisi

The actor is known for his roles in Avatar and Saving Private Ryan, and he's got a twin sister who has her own fashion line.

8. Charles and Max Carver

You may know Charles as Ethan from Teen Wolf, but maybe you'll also recognize the pair as tiny tots running around in Desperate Housewives.

9. Aaron and Shawn Ashmore

Shawn's been in a few X-Men films, and Aaron acted in Smallville. The two look so alike you'd think they were the same person!

10. Tiki and Ronde Barber 

The American football stars are similar but still different – Ronde playing cornerback and safety for the Tampa Bay Buccaneers, while Tiki was a running back for the New York Giants. Same-same but different.

11. Vin Diesel and Paul Vincent

This one always surprises people. The action movie star has a relatively normal brother, who works as a film editor.
